Saclay Nuclear Research Centre
The CEA Paris-Saclay center is one of nine centers belonging to the French Alternative Energies and Atomic Energy Commission (CEA). Following a reorganization in 2017, the center consists of multiple sites, including the CEA Saclay site (formerly a "center"), the Fontenay-aux-Roses site and the sites of Paris, Genoscope, Évry, Orsay and Caen. Historically, as the main Saclay site was the heart of French nuclear research it was called Saclay Nuclear Research Center prior to the shift towards other fields of research and innovation besides nuclear. The center has close ties with Paris-Saclay University, being located on the Saclay plateau and active in the Paris-Saclay, Paris-Saclay project for innovation. Organization Since February 2017, various sites were grouped together to the CEA Paris-Saclay center, including * Saclay site (formerly a "center") * Fontenay-aux-Roses site * Paris site * Évry site (Genoscope) * Orsay site (Service Hospitalier Frédéric Joliot, SHFJ) * Caen ...

Nonprofit Organization
A nonprofit organization (NPO), also known as a nonbusiness entity, nonprofit institution, not-for-profit organization, or simply a nonprofit, is a non-governmental (private) legal entity organized and operated for a collective, public, or social benefit, as opposed to an entity that operates as a business aiming to generate a Profit (accounting), profit for its owners. A nonprofit organization is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. Depending on the local laws, charities are regularly organized as non-profits. A host of organizations may be non-profit, including some political organizations, schools, hospitals, business associations, churches, foundations, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be Tax exemption, tax-exempt, and some may also qualify to receive tax-deductible contributions, but an enti ...

Radiolysis
Radiolysis is the dissociation of molecules by ionizing radiation. It is the cleavage of one or several chemical bonds resulting from exposure to high-energy flux. The radiation in this context is associated with ionizing radiation; radiolysis is therefore distinguished from, for example, photolysis of the Cl2 molecule into two Cl- radicals, where (ultraviolet or visible spectrum) light is used. The chemistry of concentrated solutions under ionizing radiation is extremely complex. Radiolysis can locally modify redox conditions, and therefore the speciation and the solubility of the compounds. Water decomposition Of all the radiation-based chemical reactions that have been studied, the most important is the decomposition of water. When exposed to radiation, water undergoes a breakdown sequence into hydrogen peroxide, hydrogen radicals, and assorted oxygen compounds, such as ozone, which when converted back into oxygen releases great amounts of energy. Some of these are explosive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intergovernmental Panel On Climate Change
The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations. Its job is to "provide governments at all levels with scientific information that they can use to develop climate policies". The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) set up the IPCC in 1988. The United Nations General Assembly, United Nations endorsed the creation of the IPCC later that year. It has a secretariat in Geneva, Switzerland, hosted by the WMO. It has 195 Member states of the United Nations, member states who govern the IPCC. The member states elect a bureau of scientists to serve through an assessment cycle. A cycle is usually six to seven years. The bureau selects experts in their fields to prepare IPCC reports. There is a formal nomination process by governments and observer organizations to find these experts. The IPCC has three working groups and a task force, which carry out its scientific work. The IPCC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nobel Prize In Physics
The Nobel Prize in Physics () is an annual award given by the Royal Swedish Academy of Sciences for those who have made the most outstanding contributions to mankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901, the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. Physics is traditionally the first award presented in the Nobel Prize ceremony. The prize consists of a medal along with a diploma and a certificate for the monetary award. The front side of the medal displays the same profile of Alfred Nobel depicted on the medals for Physics, Chemistry, and Literature. The first Nobel Prize in Physics was awarded to German physicist Wilhelm Röntgen in recognition of the extraordinary services he rendered by the discovery of X-rays. This award is administered by the Nobel Foundation and is widely regarded as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attosecond Physics
Attosecond physics, also known as attophysics, or more generally attosecond science, is a branch of physics that deals with light-matter interaction phenomena wherein attosecond (10−18 s) photon pulses are used to unravel dynamical processes in matter with unprecedented time resolution. Attosecond science mainly employs Femtochemistry#Pump–probe spectroscopy, pump–probe spectroscopic methods to investigate the physical process of interest. Due to the complexity of this field of study, it generally requires a synergistic interplay between state-of-the-art experimental setup and advanced theoretical tools to interpret the data collected from attosecond experiments. The main interests of attosecond physics are: # Atomic physics: investigation of Electronic correlation, electron correlation effects, photo-emission delay and Tunnel ionization, ionization tunneling. # Molecular physics and molecular chemistry: role of electronic motion in molecular excited states (e.g. Charge-tra ...
